AT&T says it will no longer exempt HBO Max from mobile data caps starting March 25, after a US court upheld CA's net neutrality law; change will apply beyond CA
- AT&T will no longer exempt viewing of its HBO Max streaming service from data caps after a federal court upheld California's …
Context & Ripple Effects
AT&T had already used data-cap exemptions to favor its own video properties, first through DirecTV’s exempt mobile viewing and later by placing HBO Max in its sponsored-data program while rival streaming services continued to count against caps. FCC scrutiny of the DirecTV arrangement had previously identified the practice as a potential net-neutrality problem.
The court decision upholding California’s law now coincides with AT&T ending the HBO Max exemption not only in California but more broadly, reversing a long-running distribution advantage for its owned streaming service.
First-order effects
- HBO Max viewing on AT&T mobile plans will begin counting toward subscribers’ data caps on March 25, removing a usage-cost advantage AT&T had provided to the service.
- AT&T changes its sponsored-data treatment beyond California following the court’s validation of California’s net-neutrality law.
Second-order effects
- Netflix, Disney+, and other streaming services no longer face the specific disadvantage of competing against an HBO Max offer whose mobile viewing was exempt from AT&T data caps.
- AT&T’s move weakens the commercial value of carrier-controlled zero-rating as a way to steer mobile video consumption toward affiliated services.
Third-order effects
- If carriers respond similarly to enforceable state net-neutrality rules, competition in mobile video shifts further toward service quality and subscription terms rather than preferential data-cap treatment.
- The reversal reinforces a regulatory model in which state-level net-neutrality enforcement can shape nationwide carrier policies when providers choose a single broader approach.
The trend: State net-neutrality enforcement is narrowing carriers’ ability to use data caps to favor affiliated digital services.
